WASHINGTON, August 31. /TASS/. It is important to clear up the situation surrounding Washington's new decisions on Russia's diplomatic missions in a cool-headed manner and without hysterics, the new Russian Ambassador to the US, Anatoly Antonov stressed on Thursday.

"We need a cool, clear-headed and professional course of action now," he told reporters upon arrival at the Dulles International Airport.

On Thursday, the US demanded that Russia close down three of its diplomatic facilities on American soil, claiming the move stemmed from its willingness to maintain a diplomatic balance.
